Hi RSR

The Theme doesn’t need the actual size. The Theme is designed to get the images fit and covered according to the layouts. But based on demo we have used 1500px X 300px for Header image, 800px X 480px for Post featured Image and you can use min 400px for Logo. Also it would be better if you compress the image file size before upload. You can find various online Image compressor to compress the Images file size and they won’t affects the quality of images.

Thanks
